SILAS JENNISON HARWOOD, OF DORSET, VERMONT, ASSIGNOR OF ONE- TENTH TOGEORGE L. WOODCOCK, OF MANCHESTER, VERMONT.

CLOTH WATERPROOF.

SPECIFICATION forming part of Letters Patent No. 625,030, dated May 16, 1899. Application filed July 24:, 1897- Sorial No. 645,838- (No specimens.)

T0 (ZZZ whom it may concern:

Be it known that I, SILAS J ENNISON HAR- WOOD, acitizen of the United States,'residing at Dorset, in the county of Bennington and State of Vermont, have invented a certain new and useful Process of Making Oloth Waterproof, of which the followingis a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention consists of an improved process for treating cloth or textile material so as to render the same waterproof; and the object thereof is to provide an improved process for this purpose whereby an ykind or class of textile material may be rendered waterproof, a further object being to provide an improved process for rendering large pieces of cloth or textile material Waterproof, so as to adapt the same for use as a covering for articles of various kinds.

The invention is fully disclosed in the following specification, and in the practice thereof I provide a suitable cloth or piece of textile material which it is desired to render waterproof and immerse the same in boiled linseed-oil, enough of which is provided to thoroughly saturate the cloth. The cloth is then wrung by hand or run through a wringer to get. out the surplus oil, so that the cloth will not drip when hung up to dry, and the said cloth is preferably dried by being hung on wires or laid on wire-netting. WVhen the cloth is thoroughly dry, after being treated as above, I apply to the right side thereof by means of a flannel cloth a solution composed of one gallon of boiled linseed-oil and two ounces of turpentine, this solution being rubbed into and over the right side of the cloth by means of a flannel cloth or rubber, as described. The cloth is then thoroughly dried, as in the first instances, and when again dry I apply to the Wrong side thereof by means of a flannel cloth a solution consisting of one gallon of boiled linseed-oiland one ounce of oil of turpentine, after which the cloth is again allowed to dry. 1

If proper care has been taken in oiling the cloth on both sides, as herein described, the said cloth will be in condition to furnish a first-class covering for hay-stacks, strawstacks, and various other articles for which color and of-any desired amount, to which is added a requisite amount of alcohol, and these ingredients, after being thoroughly mixed, are placed in a vessel, preferably composed of glass or similar material, and covered with alcohol, and said vessel is sealed and allowed to stand for about twenty-four hours. The covering of alcohol is then poured off, and the remaining paste is mixed with enough boiled oilto give the required thickness,which is applied to the cloth by being rubbed thereon, as hereinbefore described. The purpose of mixing the dry paint or powder with alcohol is to toughen the paint or powder, so that when it is mixed with the boiled oil and applied to the cloth it will not crack or flake 0E from the cloth. This treatment gives the cloth a finish which is soft and pliable, and the oil-cloth thus produced may be used for any desired purpose.

Having fully described my invention, I claim as new and desire to secure by Letters Patent-- The herein-described process for treating cloth or textile material so as to render the same waterproof and preserve its pliable features, said process consisting in immersing the cloth or material in boiled linseed-oil, then drying the same, then rubbing the right side thereof with a solution composed of boiled linseed-oil and turpentine, then drying the same again, then rubbing the wrong side thereof, with a solution composed of boiled linseed-oil and turpentine, then drying the cloth or material again and then applying thereto a mixture of boiled oil, dry powder or paint and alcohol, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of the subscribing witnesses, this 20th day of July, 1897.

SILAS JENNISON I-IARWOOlD.
